MANIFOLD VALVE.

SPECIFICATION forming part of Letters Patent No. 456,546, dated July 28,1891.

Application filed $eptember 17,1890. Serial No. 365,219. on model.)

To all whom it may concern.-

Be it known that I, ALBERT BLANKERTs, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan,

have invented a certain new and useful Improvement in a Manifold Valve;and I declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit apperxo tains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in valves,and more par- [5 ticularly in manifold valves; and it consists of thedevices and appliances hereinafter specified and claimed, andillustrated in the ac companying drawings, in which- Figure 1 is ahorizontal section, and Fig. 2 a vertical cross-section, of a deviceembodying my invention. I-Ieretofore as manifold valves have commonlybeen constructed the valve-stems have projected through the channel ofthe supplypipe, and the valves have been seated in a suitable valve-seaton the side of the channel opposite that from which the valvestementers. This has necessitated the use of stuffing-boxes exposed to thepressure of the gas, 0 on account of which leakage of gas has frequentlyresulted, especially when the valves are closed. My invention isintended and adapted to overcome this difficulty by providing thesupply-pipe with manifold valves 3 5 so constructed and arranged as toprevent gaspressure from exerting its force upon any stuffing-boxes, andconsequently overcome any liability of leakage.

I carry out my invention as follows:

A represents a supply-pipe provided with screw-tapped arms A for theengagement of any desired connection therewith.

A denotes, also, screw-tapped arms communicating with the channel a ofthe supply- 5 pipe and constructed for the engagement of the individualvalves B therewith. The inner end of the orifice a in the arms Arespectively, are preferably contracted and formed into a valve-seat, asshown at a Running about the channel aof the supply-pipe in the castingis a cored passageA communicating with the arms A and A respectively,the arms A being closed off from direct communication with the channela, as by a diaphragm a. By this construction it is evident that thesupply must pass first through the orifice a at the valve-seat a thenceinto the cored passage A and into the arm A. It is only necessary thusto control the admission through the orifice a and thence into the cored6o passage. This is done by seating the valve B upon the valve-seat (LThe valve, as shown, is constructed with a valve-stem B, provided withan operatinghandle B and a valve-head Z) to seat on the valve-seat. Avalve -case 1-3 has a screwthreaded engagement with the arm A and isprovided with a customary cap I), through which the valve-stem projects.The construction is very simple and efficient. I

I would have it understood that I do not limit myself to any particularform of the separate valve B employed.

As soon as the valve is opened the pressure is relieved. When closed, nopressure comes into contact with the stuifing-box. Nor do I limit myselfto the number of said valves B employed, as my invention contemplatesone or more valves in combination with the supply-pipe so constructed.

\Vhat I claim as my invention is The combination, with a manifoldsupplypipe having a free passage throughout its length, of a series ofarms A A arranged in communicating pairs, the arms of one series 8respectively comm unicating with the passage in the manifoldsupply-pipe, cored passages A in the body of said supply-pipe, eachcommunicating with one pair of said arms, valves located in one of saidseries of arms seated, respectively, between one extremity of the coredpassage and the communication of the arm with the passage of thesupply-pipe, each valve independently controlling the communication ofthe passage in the supply-pipe 5 through a communicating pair of arms,whereby the supply from said manifold supplypipe through anycommunicating pair of arms can be controlled by its corresponding valveindependently of the other valves and without obstructingthe passage insaid manifold supply-pipe, substantially as set forth.

In testimony whereof I sign this specification in the presence of twowitnesses.

ALBERT BLANKERTS.
